I just cleaned/moved my navel hoop for the first time, and I don't remember this much sensitivity from it from the last time. I think it's also a smaller hole than the last time. Ther's some redness too (very little and mild) I hope thats normal, I'll have to look at the info they gave me. Anyway I love the piercing anyway.
when it is red in the beginning that is very normal. It is still sore and healing. Good Luck!
